In the world, especially in the USA, Germany, Sweden, Japan, South Korea, China, Russia, Ukraine, Belarus and other developed countries, special attention is paid to the development of hydraulic systems of tractors and mobile machines in the field of road facilities. construction and agriculture. At the same time, the development of graphic-analytical, differential and analytical methods based on the universality of connecting parts of equipment installed in hydraulic systems (bucket, trowel, drill, crane), through the use of scale factors of speed and readiness when bringing the hydraulic system into a multi-purpose machine into a single system, the dynamic model of the hydraulic system of a multi-purpose machine and the improvement of methods for determining the static and kinematic parameters of the equations of motion are considered one of the topical issues. In this regard, it is important to bring multi-purpose machine hydraulics into a single hydraulic system in every developed country. This article analyzes multi-purpose machines developed in the countries of the world and the issues of their adaptation to the conditions of our country.
